Lighthouse of Alexandria

The Lighthouse of Alexandria was a lighthouse built by the Ptolemaic Empire of Egypt from 280 to 247 BC. Located in Alexandria, Egypt, it was one of the Seven Wonders of the Ancient World, and it was one of the tallest man-made structures in the world at times. From 956 to 1323, it was thrice badly damaged by earthquakes, and it became an abandoned ruin. In 1480, the last of its remnant stones were used to build the Citadel of Qaitbay, and it was later submerged by the sea.
